ENGINE & COOLING:To start out with is the new all aluminum 550 horsepower and 510 ft.-lb. of torque engine, this is a 10 horsepower increase over the 2010 distinguished by it's silver SC and FGT Blue valve covers.http://i189.photobucket.com/albums/z...ine01_HR-1.jpg

The all-new 5.4-liter all-aluminum engine is also 102 pounds lighter than the previous cast-iron engine and due to it’s “SprayBore” Ford-patented plasma transfer-wire arc coating technology (PTWA). It has better cooling efficiency due to it’s superior wear resistance and reduced cylinder wall to piston friction. http://i189.photobucket.com/albums/z...ine06_HR-1.jpg

Added to that is a new two-row intercooler that delivers 40% better thermal efficiency so this car will perform with optimum potential even on the hottest of track days.

This 2011 Gt500 is the first modern day Shelby that does not have a “Gas Guzzler Tax” added to the cost of the car, thanks to an EPA estimated 23 mpg hwy and 22 mpg city gas milage. This is up from 22 mpg hwy, 14 mpg city on the 2010 model.

Much of that hp and fuel efficiency increase is attributed to the larger 2-3/4” exhaust, the addition of Electric Power Assist Steering (EPAS), 120 lb overall weight savings (coup) and improved aerodynamic changes to the underside of the car.http://i189.photobucket.com/albums/z...ive---19-1.jpg

HANDLING:

SVT engineers looked at the handling package as a whole, the sum of the parts if you will.

To start out with SVT engineers worked directly with Goodyear to develop tires that would offer superb wet or dry traction and precise handling. They would be complete with a race-inspired high-performance tread compound.The tire is the all new Goodyear Eagle® F1 SuperCar G: 2 tire. http://i189.photobucket.com/albums/z...e---12-1-1.jpg

Both front and rear sway bars were improved as well with the rear being the largest one they could fit into the platform.

The standard 355 rear differential was also increased to the optional 373’s to help increase corner exit acceleration.

The SVT Performance Pack also includes a new spoiler with a larger “Gurney Flap” which adds 2% more drag in the rear but with the help of new aerodynamic ducting the front has an additional 18% more down force over the 2010 model reducing understeer.http://i189.photobucket.com/albums/z...ive---06-1.jpg

All of these changes add up to improved driving dynamics, balance, grip and handling which translate into faster track times and 1.0 'G' on the skid padSo much so that according to Ford , a 2011 equipted with the SVT pp was a full 3 seconds faster on a 2.3 mile road course over the 2010 model and it's 0 to 60 times were 1/10th quicker and it's 1/4 mile times were 2/10ths faster

Braking distance’s have also decreased by 7% in both 0-60 and 0-100 stopping . Slotted brake dust shield’s were added to improve brake cooling as well.
